Adjustable Gas Sensor for – Hydrogen (H2), LPG, Methane-natural Gas (CH4), Carbon Monoxide (CO), and Alcohol. Detects 300-10,000PPM

MQ-5 liquefied gas Methane Gas Sensor Module

Overview

Suitable for home or industrial on LPG, natural gas, coal gas monitoring devices. Excellent resistance to alcohol, smoke interference.

Features

• Using high-quality dual-panel design, with power indicator and TTL signal output instructions;
• With a DO switch signal (TTL) output and AO analog signal output;
• TTL output valid signal is low. (When the output low signal light can be directly connected microcontroller or relay module)
• The analog output voltage, the higher the concentration the higher the voltage.
• For gas, natural gas has better detection sensitivity.
• There are four screw holes for easy positioning;
• Product Dimensions : 32 x 20 x 22
• With a long service life and reliable stability
• Rapid response and recovery characteristics
